How many Coulombs of charge pass through a 95W amplifier plugged into 110V wall socked over the course of a 2 hour concert?

• Science -

Multiply the current in Amps (Power/Voltage) by the number of seconds (7200).

Actually the same charge will go back and forth, since it is certainly an AC circuit.

• Science -

75240000 Coulombs
